Fig. 2: Nature-nurture model fitting of real-world networks.

A–P The observed degree distribution P(k) (blue) and degree-ratio distribution P(η) (red) in 32 real-world networks (other 16 in Supplementary Fig. 2) are fitted based on Eqs. (2) and (3) of the nature–nurture model. The parameters N and T match the number of nodes and links in the empirical data. The other fitting parameters, \({\omega }_{\max }\), α, and b are provided in Supplementary Table 2.
